AISAT is basically the roleplaying game of The David Tennant Years (although we don't forget Christopher Eccleston or his predecessors, even if the artwork does). This is a game with the lush high quality production that one might expect from an officially BBC licenced Doctor Who product, but how does it stand up?
Pretty well, if all things are considered.
This product aims itself squarely at fans of Doctor Who and relies on the idea that existing RPG aficionados will be intrigued enough to pick it up. For those experienced gamers I'll lay it on the line that this is a great little system (if phenomenally basic) that makes a Time-Lord-Saving-The-Universe-Pseudo-Science out of hand-waving the rules, but does so in a nice way that encourages the games master and the players to work co-operatively to tell a great story. The primary balancing point in the rules comes down to Story Points- want to play a Time Lord, powerful alien, or immortal like Jack Harkness you will have less of these and they allow you to influence everything from roll results to those big dramatic moments when the Doctor returns to his youthful appearance and shows the Master who's boss.
